Abstract: Polymeric anise oil resin(PAOR)was synthesized with anise oil under the condition of AlCl3 as catalyst,ethyl acetate as solvent,stirring reaction for 4 h at room temperature.The average molecular weight of PAOR was measured.Its structure was analyzed by IR and UV,and its application on the adsorption of the orange peel pigment was studied.Experimental results showed that the average molecular weight of PAOR was 1.02×103.IR of PAOR was distiquished from standard IR of anise oil by that PAOR absorption peak(965 cm-1)became much weak,three new peaks appeared from 800 to 700 cm-1.UV absorption peak of PAOR with a hypsochromic shift of 11 nm by comparison with anise oil showed the CC bond of anise oil joined in polymerization.The use of PAOR to adsorb orange peel pigment was also studied by column chromatography.The column was then washed with H2O to remove the impurity,followed with 95% C2H5OH to wash off the orange peel pigment.PAOR had good adsorption to the pigment,and could be used several times.The adsorption ability was kept 75% after using six times.
Key words: polymeric anise oil resin, orange peel pigment
